TLSC 07050 542816 Adjustable (60-90 Degrees °C) Dual Immersion Thermostat - Twin Control and Manual Reset high Limit stat for Oil Fired Boiler.

i,m a plumber and got this to replace a problem stat on a job.when it arrived i noticed that the high limit reset pin under the black cap was out and wouldnt stay in when pushed as previous types of boiler stat would remain in flush when in the set position and pop out when triggered.i tested it with a hot air gun and it did click and break the circuit to the pilot light when heated,then i placed in cold water and pushed the reset pin, it clicked but didnt remain in flush, the circuit was reconnected so it,s working as it should.it was just confusing that the pin didnt remain flush which was always the case on older types of limit stats.

Replacement, works fine, bit fiddly to connect

I havent fitted it yet

The wiring diagram leaves a lot to be desired and certainly confused experienced electrical engineers

Like for like replacement of the old unit. Easy to fit. Works perfectly.

The quality of the product is very good and seems quite robust👋. I found it easy to install and not sure why in some other review somebody was complaining about wiring. The product I've received is slightly different than the advertise pictures and offers temperature regulation between 0 to 90 °C ( in advertise says 60 to 90 °C). I don't mind as offers more control in lower temperature. Took me about 1h to install💪 and working fine. I cannot say if overprotection at 90°C works as now my boiler stops at 60°C 😉

i got my order and when i opened it the thermostat pocket was missing without it i can not put my heating on

Easy to fit.I needed to exchange with a faulty part on my ancient boiler.
